[Harry Potter/TR] Milk on a Stone

The title comes from a famous line by Yeats, "Milk Spilt on a Stone" (I'm one of those people who can't help showing off what they've read). The premise: During the war, Voldemort and Harry secretly fell in love (once again, I'm skipping over how they fell for each other). Only a few members of the Order of the Phoenix and the Death Eaters know. But during a fierce battle in the Department of Mysteries at the Ministry of Magic, Voldemort, while protecting Harry, accidentally falls into some mysterious substance and turns into a baby (I remember there was something like this in the fifth book). Voldemort has lost all his memories and is now a real baby version of Tom Riddle. To protect little Tom, Harry and the others who know the truth keep it secret. They announce to the public that Voldemort is dead, and little Tom is adopted by Hermione and Ron, who recently got married. He becomes Tom Weasley, while Harry leaves for a distant land. Warning: SE (sort of). A short-to-medium-length story.
